Conversion formula

The conversion factor from decimeters to kilometers is 0.0001, which means that 1 decimeter is equal to 0.0001 kilometers:

1 dm = 0.0001 km

To convert 4220 decimeters into kilometers we have to multiply 4220 by the conversion factor in order to get the length amount from decimeters to kilometers. We can also form a simple proportion to calculate the result:

1 dm → 0.0001 km

4220 dm → L_(km)

Solve the above proportion to obtain the length L in kilometers:

L_(km) = 4220 dm × 0.0001 km

L_(km) = 0.422 km

The final result is:

4220 dm → 0.422 km

We conclude that 4220 decimeters is equivalent to 0.422 kilometers:

4220 decimeters = 0.422 kilometers

Alternative conversion

We can also convert by utilizing the inverse value of the conversion factor. In this case 1 kilometer is equal to 2.3696682464455 × 4220 decimeters.

Another way is saying that 4220 decimeters is equal to 1 ÷ 2.3696682464455 kilometers.

Approximate result

For practical purposes we can round our final result to an approximate numerical value. We can say that four thousand two hundred twenty decimeters is approximately zero point four two two kilometers:

4220 dm ≅ 0.422 km

An alternative is also that one kilometer is approximately two point three seven times four thousand two hundred twenty decimeters.
